Do you feel the need for speed, but don’t need a full sized car? That’s how R/C fanatic Nic Case is. He secured a world record for the fastest R/C car. That car is called the R/C Bullet, a one-tenth scale car that has reached a top speed of over 188 mph.
Nic Case didn’t take the R/C record from anyone else either. He was the holder of the previous record at 171.97 mph and took it from himself. The R/C Bullet isn’t made from parts you can buy from your local hobby store either. Not surprising considering the speeds we are talking about. Most of the car is custom designed and fabricated to be as light and sturdy as possible.
The entire thing weighs just 10 pounds and generates 10 horsepower from its electric motors. One of the main challenges with this design was getting all that power transferred to the wheels. The problem is that the car moves so fast it’s easy to produce lift that reduces tire efficiency. So he used a low-profile scoop-shaped body and larger 3-inch tires to counter the effect.
Another problem is that when the car gets up to speed, the motor spins so fast that it threatens to throw the vehicle off target. So the team added a heavy brass weight to the drive shaft that counters the inertia of the motor. He thinks he can reach 200 mph if he continues to modify the design.
